JAMES c. BEARDSLEE. AND WILLIAM J. CRITOHLEY, OF CLEVELAND,

OHIO, ASSIGNORS TO CLEVELAND, OHIO,

To all w/wmp't may concern: Be it known that we, J AMES O.- BEARDSLEEand; WILLIAM J ORIroH EY, citizens of the United States, and residentsof Cleveland, county of Ouyahoga, and, State of Ohio, have inventedanewvand useful Improvement in heel Painting Machines, of which the following is a specification, the principle of the invention being hereinexplained and the best mode in which-Wehave contemplated applyingthatprinciple, so as to distinguish it from other inventions. I e I Ourinvention pertains to improvements in devices for mechanically paintingwheels and directionin orderto spread the-paint thoroughly over theobject? s surface, aswell as to removeby the action of the centrifugalforce thus developed any surplus ofpain't, such as would otherwiseremain and mar. thecoat.

The object of the present invention is to I provide in connection withthe tank and description setforth in anism embodying the invention,such,,disclosed means constituting but one of thevahood usuallycharacterizing machines ofthis kind suitable mechanism whereb wheels orother objects can be more quick y and economically handledandsatisfactpry results therewith more. uniformly assured than has beenpossible with machines at present 'on the market. Said invention is amodification ofthe device described and claimed in apending applicationof one of the present inventors for. Letters Patent of the UnitedStates, filed April 23,1906, Serial No.:313,22 5; and. it consistspf-means hereinafter fullydescribed and particularly set forth in the.claims.

viewed from the right in 1," and Fig. 3 is a plan view of such machine.a I a The preferred form of paintreceptacle (shown .in the abovefigures) comprises a semicircular metallic tank A, the relatively narrowbody portion of which is provided with a broad flaring top or rim 1. Theradius of the tank-body should be great enough to permit the readyaccommodation therein of the largest wheel upon which itjis desired tooperate, there being recesses'or pockets 0, in the flaring rim a of thetank adapted to receive the hub of the wheel when the latter is loweredinto the tank. It is designed that such tank be sunk into a'recessinthefloor in order to save space and render all parts of themachineproper more accessible. When thus sunk into the floor, the tank restsupon a flange a that encircles the same a short distance below rim a,This flange also serves as a convenient point for the attach merit tothe tank of handles a whereby the tank may be removed from its positionin the floor when desired. The purpose of this con struction is topermit the ready changing from one kind of paint to another withouthaving to use a different machine with each r going through a bothersomeprocess of empt ing'the tank of the one paint, cleansin the same, andthenfilling it" with the ot er. Here it is merely necessary to exchangeforietank for-another, therebeing as many tanks, as there are colors orkinds of paint in regiilaruse The tanks, moreover, afford convenientreceptaelesfor temporarily storing the paint fh'eliino't being used, andcovers maybepfrovided therefor to lessen the loss fr om evaporation whenthey are standirigid l,e.,,, ,1 i

We iise connection with the tank just a removable hood of familiar form,and hence I not illustrated Such hood is preferably made of sheet metaland its width s thesame as that of the rim surmOunting tankA, and itsheight is such 'as. to readily accommodate a wheel whenthe' latt'er israised entirely above the of the paint in tank A. Such hood is alsousually made of triangular cross-section, w ereby it is adapted tofacilitate the collection and return to the tank of the paint whenthrown ofl bythe rapid rotation of the wheel the hood.

To support the wheel, both while being immersed in the paint-tank andwhile being rotated within the hood, we provide the following mechanism:Laterally of the tank, or, rather, the recess in the floor in which suchtank is placed when in use, and to one end of the same are securelymounted, on a suitable base C, two upright standards a. In bearin s c onstandards a is journaled a horizonta drive-shaft C the rear end of whichprojects some distance beyond the corresponding bearing and is providedwith a'driving-pulley C Intermediately of the two standards 0 there ispivotally mounted on such driveshaft C a frame C, preferably consistingof an integral'casting of general U shape. The pointof pivotal supportof frame Cbeing near thebase of the U the armsare caused toprojectalongside tank A, Figs. 1 and 3, and their length is so proportioned asto bring their ends substantially in a plane passing through the centerof such tank and superimposed hood B. In suitable bearings 0 provided inthe ends of these arms of frame C, is-journaled a spindle C Spindle Cwill obviously lie parallel with drive-shaft C and its-forward endprojects out over tank A and withinhood B when the latter is inposition. Such forward end of the spindle is designed to: receive thewheel to be painted, thehub of the wheel being slipped directly onto thethe same. To hold such wheel rotatively upon the spindle when the latteris being rotated, arms a are mounted near the spindles end and are bentforwardly to engage the wheel between its spokes. The outer end of eachof these arms is spread in the manner clearly shown in Figs. 1 and 2,whereby any tendency of the wheel to slip off the spindle pending suchrotation is overcome.

From the description previously iven of the mannerin which frame C isosci latorily mounted u on drive-shaft C it will be evident that t eformer may be-swung up and down to raise and depress the spindle Cmounted in its outer end, as desired. This swinging motion, of course,is entirely independent of any motion of rotation that may be given theshaft C through driving-pulley C Normally the frame is maintained in itsraised position, illustrated in the several figures of the drawings, bya counterweight C adjustably secured on a bar C projecting outwardly,form the frames base. Such counterweight is intended to be sufficientlyheavy to maintainthe'frame in the position indicated even when a wheelisattached to spindleG. To swing the frame to depress its outer end, soas to immerse such wheel in tank A, a handle 0 is conveniently attachedto counterweight C In order to steady frame C a ainst undue vibration towhich it might be iable when in its raised position, and particularlywhen spindle C is being rotated, a'standard D, provided with ahalfbearing (1, is positioned so as to permit the spindle to lie thereinwhen the frame is tilted upwardly. This bearing-rest, in addition tosteadying the frame, serves also as a stop to prevent the same fromswinging too far. While only one such standard D is shown, this, whendisposed so as to engage the spindle midway between its ends beingconsidered sufficient, two or more rests may be provided, if desired.

To effect the reversible rotation of spindle C with attached Wheel, suchas has been described as being most efficacious in securing the even andthorough spreading of the paint, the spindle is operatively connected byany suitable means with drive-shaft The approved form of connection hereshown comprises a pair of pulleys C C rotatably mounted upon thedrive-shaft and respectively connected to rotate in opposite directionstwo similar pulleys C and C", rotatively mounted upon the spindle. Bothsets of pulleys are obviously most conveniently mounted on that portionof their respective shafts inclosed between the arms of frame 0. Adouble-cone friction-clutch C splined on drive-shaft C intermediately ofpulleys C and C and shiftable into contact with either of said pulleysby a hand-lever 0, enables the operator to easily connect spindle C withshaft C to drive the former in whichever direction desired and atvarying rates of speed up to the maximum speed of the shaft. Normallyhand-lever a is held by springs c to retain friction-clutch C in aneutral position out of contact with either of pulleys C Q.

As to the manner in which our im )roved. wheel-painting machine isoperated ut little need be said, such operation having been in largepart indicated in connection with the foregoing description of themachines construction. It will' suflice, accordingly, to point out thatnormally the wheel-supporting spindle C is maintained in the'elevatedposition shown in the figures, in which position a wheel may be attachedthereto with the greatest facility. Ordinarily one operative wouldattend to thus afiixing and removing the wheels, while another wouldswing the frame and mani ulate hand-lever c". A wheel having been t iusattached by the first o era'tive the second thereupon grasps handl e cto depress the frame, and thereby dip the wheel in the tank. While thussemi-immersed, the wheel is given several turns, either by hand or by aslight pressure on lever 0, it being of course-understood that too rapida rotation of the wheel when in this'position would be disastrous. Bysimply releasing handle 0 the frame is allowed to swing back to itsnormal position, and thereby raise the wheel, which is thereupon rapidlyrotated in first one direction, then the other, by swinging hand-lever cto shift clutch C with greater pressure than in the instance alreadynoted into then the other, of sim ly releasing a C i; disconnected andas soon as the may be removed and another substituted therefor.

Our machine, it is hence seen, permitsan increase in the rapidity andconsequent economy with which wheels can be painted. At the same time,by virtue of the arrangement of the several parts, the labor of handlingthe wheels, involved in utting them on and removing them from t emachine, is greatly reduced, while by the fewness and simplicity inconstruction of the parts themselves the initial cost, as well as theexpense of repairs, is reduced to a minimum.

Having thus described our invention in detail, that which weparticularly point out and distinctly claim is.
